Patent number: 10717262Abstract: Disclosed is a method for unpacking a component 16 manufactured by means of a generative manufacturing process, from a particulate material fill 18. In the method, an auxiliary frame 20 having a vertical circumferential wall structure 22, open downward, is arranged above a vertical circumferential wall structure 12 of a construction box 10. In addition, a construction platform 14 of the construction box 10 is displaced upward, so that the particulate material fill 18 containing the component 16 is transferred from the construction box 10 to the auxiliary frame 20. In addition, the auxiliary frame 20 with the particulate material fill 18 containing the component, and the construction box 10 are moved away from each other, and the component 16 is unpacked from the particulate material fill 18 at least in part and is removed from the auxiliary frame 20.Type: GrantFiled: August 28, 2015Date of Patent: July 21, 2020Assignee: ExOne GmbHInventors: Rainer Höchsmann, Alexander Müller, Sven Klaua, Maximilian Baumann, Wolfgang Seeger, Renate Ratzenberger, Lisa Huber

Patent number: 10695954Abstract: A coating device arrangement 1 for a 3D printer is disclosed, comprising a coating device 3 having a container 17 defining an inner cavity for receiving particulate construction material which leads to an opening for outputting the particulate construction material, and a stroking member 15a, by which a stroking surface is formed which is directed downward, and which is configured to stroke over construction material output from the opening using the stroking surface to thereby level and/or compress the output particulate material. The coating device arrangement 1 further comprises a setting device 13 which is configured to variably set an inclination angle of the stroking surface 15a.Type: GrantFiled: August 25, 2015Date of Patent: June 30, 2020Assignee: ExOne GmbHInventors: Rainer Höchsmann, Alexander Müller, Sven Klaua

Patent number: 10507592Abstract: A 3D printer is described which is configured to build up a three-dimensional component in layers by forming layers of particulate construction material lying one upon the other and by selectively solidifying a partial region of the respective construction material layer. The 3D printer is configured to build up one or more first three-dimensional components in a first construction space and simultaneously one or more second three-dimensional components in a second construction space which is arranged adjacent to the first construction space. The 3D printer has a coating device arrangement which is displaceable across the first and the second construction space and a printing device which is displaceable across the first and the second construction space.Type: GrantFiled: May 6, 2019Date of Patent: December 17, 2019Assignee: ExOne GmbHInventors: Rainer Höchsmann, Alexander Müller, Sven Klaua
